My Personal Experience
The first time I made this fudge, I was nervous. Could it really taste like traditional fudge with almost no points? I remember melting the sugar-free chocolate chips and peanut butter in my small saucepan, stirring carefully to avoid clumps. The moment the mixture set in the fridge, I cut a square, took a bite, and nearly fell off my chair. Creamy, rich, and decadent—all without the calorie guilt. My husband, not following WW, even asked for seconds! This little fudge has since become a staple whenever I need a quick sweet fix.
Required Equipment
Small Saucepan
Essential for gently melting your peanut butter and chocolate together. Avoids scorching compared to a microwave.
Mixing Bowl
A heatproof bowl helps you combine ingredients without them cooling too fast.
Spatula
A silicone spatula works best to scrape all the fudge out and prevent sticking.
Baking Dish
I use an 8×8-inch pan for perfect thickness. Parchment paper lining makes removal effortless.
Measuring Cups & Spoons
Accurate measurement ensures consistent texture and SmartPoints.
Ingredients & Substitutions
- 1 cup natural peanut butter – zero-sugar, unsweetened preferred for low SmartPoints
Swap creamy for crunchy for texture variation; reduces 0 SmartPoints - 1/2 cup sugar-free chocolate chips – key to low SmartPoints and richness
Dark chocolate works too, adds slightly more flavor but similar points - 1/4 cup powdered erythritol – optional for extra sweetness
Swap for stevia or monk fruit sweetener; keeps points at 0 - 1 tsp vanilla extract – flavor enhancer, 0 SmartPoints
- Pinch of salt – balances sweetness, 0 SmartPoints
Tip: All ingredients are either 0 SmartPoints or extremely low, making this fudge a guilt-free indulgence.
How to Make Weight Watchers Peanut Butter Fudge
Step 1: Prepare Your Pan
Line your 8×8-inch baking dish with parchment paper. This prevents sticking and allows for easy slicing.
Step 2: Melt Chocolate & Peanut Butter
In a small saucepan over low heat, combine chocolate chips and peanut butter. Stir constantly with a spatula until smooth. Avoid high heat—burned chocolate ruins the flavor.
Step 3: Sweeten & Flavor
Remove from heat and stir in erythritol, vanilla, and a pinch of salt. Taste the mixture and adjust sweetness if needed. Don’t worry if it’s slightly thick—that’s perfect for fudge texture.
Step 4: Pour & Chill
Pour the mixture into the prepared pan and spread evenly. Smooth the top with your spatula. Refrigerate for at least 2 hours or until fully set.
Step 5: Slice & Serve
Remove from the fridge, lift fudge using parchment, and cut into 12 squares. Each square = 1 SmartPoint.
Mini-Tip: For clean slices, dip your knife in hot water and wipe between cuts.
Common Mistakes to Avoid
- Overheating chocolate – leads to grainy texture
- Skipping parchment – fudge sticks, hard to remove
- Rushing chilling – fudge won’t set correctly
Pro Tips for Best Results
- Use natural peanut butter, no added sugar
- Ensure chocolate chips are sugar-free
- Stir slowly for smooth texture
- Optional: sprinkle with crushed peanuts for crunch (+0 SmartPoints if unsweetened)
WW-Specific Nutrition & Strategy
Peanut butter is high in healthy fats but moderate in SmartPoints when unsweetened. By using sugar-free chocolate and erythritol, this fudge fits easily into a WW plan. A single square offers indulgence without breaking your daily points budget.
Tip: Pair one square with a cup of unsweetened almond milk for a filling, low-point snack.
Variations You Can Try
- Chocolate Swirl: Mix cocoa powder into part of peanut butter before melting (+0 SmartPoints)
